It was found that only about 2% of clones met the Company’s standards for overall quality including containing both bi-allelic disruption of the TCR, proper insertion of the CAR into the TRAC locus without random transgene integrations, and no evidence of off-target genomic modifications or translocations.(3R)-piperidin-3-amine,dihydrochloride Slower growth in pesticide intermediates weighed on industrial business.
